Frequently Asked Questions
What size leaf springs do I need? The first step would be to measure your existing leaf springs. You can then confidently match the correct springs suitable for your trailer. Refer to our How to guide below for more information:
How to Measure Leaf Springs
Does upgrading leaf springs increase towing capacity? This is a question that comes up a lot, the answer is both yes and no. Trailers are rated based on their weakest component and usually, that is the bearings.
Will longer shackles lift my trailer? Yes, longer shackle plates will increase the ride height of your trailer. We offer two lengths of shackle plates suitable for 45mm springs with 63mm centre and 75mm centre holes. It is important to note that the increase is quite minimal and is not the most effective way to increase height. You will likely see gains of around 5-8mm by increasing your shackle plate length. For alternative ways to increase the height on your trailer, please give us a call on 07 3348 3822 and the team would be happy to discuss the most appropriate method for you.
Should trailer leaf springs be replaced in pairs? The reason we recommend replacing 2 springs is to avoid any difference in height across either side of the axle. A brand new spring is always going to have a stronger camber than an old and warn spring, and if this difference is significant it will result in additional weight leaning onto the older spring. This is not ideal.
